Nothing new in the world? Nothing left to discover? NASA would beg to differ. The discovery of an "enormous, off-the-charts" bloom of microscopic marine plants in the Arctic has floored scientists. And it confirms, if nothing else, that there are things on this planet not yet seen -- things that you "never, ever could have anticipated in a million years. " So says Paula Bontempi of NASA. An ocean biology and biogeochemistry program manager in Washington, Bontempi spoke with the Los Angeles Times on Friday morning about the discovery. Here's how it came about: Over the summers of 2010 and 2011, NASA's Icescape expedition was exploring the Arctic waters of the Beaufort and Chukchi seas off Alaska.

A group of scientists warned Tuesday that world leaders must act more swiftly to slow greenhouse gas emissions or risk "abrupt, unpredictable and potentially irreversible changes" from climate change. The American Assn. for the Advancement of Science's blunt report contains no new scientific conclusions. But by speaking in plain, accessible terms it seeks to instill greater urgency in leaders and influence everyday Americans. Scientists said many previous assessments have been long and ponderous, and have failed to shift public opinion on global warming.

Scientists have caught the first images of a boa constrictor consuming a 9-pound howler monkey, and they are gruesome. In the gallery above, you will see the boa constrictor ingesting the monkey head-first, bit by bit. The images accompany a study describing a play by play of the snake attack published in the journal Primates by Julio Cesar Bicca-Marques of Pontifical Catholic University of Rio Grande do Sul and his student ...

Ladies and gentlemen, the Voyager 1 spacecraft has left the solar system - or has it? Scientists are continuing to debate whether the lonesome craft has finally escaped the solar system after 35 years of travel or has simply entered a previously unknown region of solar influence. On Wednesday, a study published in Geophysical Research Letters , a journal of the American Geophysical Union, suggests that the Voyager spacecraft exited the heliosphere - that region of space dominated by solar winds and long considered to be the edge of the solar system - on Aug. 25, 2012.

Up and down the West Coast, starfish are dying. Casualties of a mysterious disease known as seastar wasting syndrome, they are dying in Alaska, deteriorating in San Diego and disappearing from long stretches in between. Death from the disease is quick and icky. It begins with a small lesion on a starfish's body that rapidly develops into an infection the animal cannot fight. Over the course of the disease the starfish's legs might drop off, or even separate from the body and start to crawl away, as you can see in the PBS news story below.

Screaming at your teenagers to discipline them can make their behavior worse - even if you otherwise have a warm family relationship, researchers say. The effects were comparable to those in studies that focused on physical punishments, the researchers said. “From that we can infer that these results will last the same way that the effects of physical discipline do,” the lead researcher, Ming-Te Wang, an assistant professor of psychology in education at the University of Pittsburgh, said in a statement.

The dark dust thrown up by human activity in the deserts of the Southwest hastens the melting of Rocky Mountain snow and ultimately reduces the amount of water flowing into the upper Colorado River by about 5%, scientists reported Monday. The lost water amounts to more than 250 billion gallons — enough to supply the Los Angeles region for 18 months, said study leader Thomas H. Painter, a snow hydrologist at the Jet Propulsion Laboratory in La Cañada Flintridge. "That's a lot of water," said Painter, whose study was published online by the Proceedings of the National Academy of Sciences.

Scientists have infused "life" into inanimate chemical compounds by flashing a blue-violet light that prompted them to assemble themselves into a crystal. The feat, described in a study published online Thursday by the journal Science, marks an important step toward creating "active" materials that can repair themselves, such as a smartphone screen that fixes its own cracks or a Kevlar vest that fills a hole made by a bullet, experts said. Showing that microscopic particles can be made to come together or break apart on their own "opens a new area for design and production of novel and moving structures," wrote the study authors, a team of physicists and chemists from New York University and Brandeis University in Waltham, Mass.

Is 2012 the end of the world? If you scan the Internet or believe the marketing campaign behind the movie "2012," scheduled for release in November, you might be forgiven for thinking so. Dozens of books and fake science websites are prophesying the arrival of doomsday that year, by means of a rogue planet colliding with the Earth or some other cataclysmic event. Normally, scientists regard Internet hysteria with nothing more than a raised eyebrow and a shake of the head. But a few scientists have become so concerned at the level of fear they are seeing that they decided not to remain on the sidelines this time.

Regarding "World Views on Global Warming Are Worlds Apart," Oct. 5: I applaud The Times for coverage of the debate over global climate change. In the attempt to portray the scope of the debate and the complexity of the scientific issues involved, however, your story curiously fails to report the broad scientific consensus on the subject. The 1995 report that is fleetingly mentioned was compiled by the world's preeminent climate scientists, and concluded that there is a discernible impact of human activities on climate.
